Blue Light
A portion of light emitted by the sun falls in the blue spectrum. Furthermore, almost all modern digital devices and LED bulbs also emit blue light. The human eye can’t block visible blue light, so over exposure can contribute to perceived eyestrain and blurred vision. Blue light blocking glasses can block that part of the blue light spectrum that can potentially be harmful and irritating for your eyes.
Here are the top 5 Reasons why you should be wearing blue light glasses:
- Prevents eye strain: Blue-light glasses can be one way to ease digital eye strain. This specialized eyewear filters blue light and increases contrast, allowing you to focus more easily and preventing eye strain.
- Reduces the risk for developing eye diseases: Too much exposure to blue light can increase your chances of developing eye diseases such as cataracts. The blue light can penetrate through the cornea (the front part of the eye) and then reach the retina (photosensitive layer at the back of the eye). Indeed, it is true that your cornea and lens can block harmful UV light from reaching your retina, but they cannot block blue light. Blue light glasses can reduce the detrimental effects of constant exposure to blue light, which will reduce your risk of getting eye diseases.
- Helps with sleep: Blue light can negatively affect your normal waking and sleeping cycles and the quality of your sleep. You may find it difficult to sleep at night and get up in the morning if your brain associates blue light with daytime. Putting blue light glasses on before sleeping while using your smartphone can also help mitigate the effects of blue light exposure.
- Protects the eyes from dryness: Even though dry eyes sound like a minor issue, they can be very distracting when trying to concentrate or driving after a few hours of screen time. In addition to this, dryness may cause you to rub your eyes excessively, causing them to be sore. Make your screen time more comfortable by blocking out the blue light by wearing blue light glasses to prevent your eyes from drying out.
- Ensures that you can use your devices longer without worrying: Most of our daily tasks require that you use your smartphone, tablet, or computer for numerous hours each day. These devices emit blue light, which bombards you continuously. Blue light glasses can protect your eyes without increasing your risk of vision problems.
